Examples
Embodiment 1
[0044] Take 0.1g of MIL-53(Al), 1g of PTFE, and 2g of carbon black in a 10mL volumetric flask, and pour it into a beaker after constant volume with DMF, stir at 140rpm for 15 minutes, take 0.3mL of the mixed solution and use a metal die to uniformly Cover it on a 4cm×1cm titanium electrode and dry it at 38°C. The section of the finished composite electrode material ( figure 2 ) and surface ( Figure 7 ) for scanning electron microscope test, and with the section of pure titanium electrode ( figure 1 ) and surface ( Figure 6 )comparing. Compared with the pure titanium electrode, the surface of the composite electrode material in Example 1 has an obvious MOFs crystal structure, and it can be seen that there is an additional modification layer in the cross section, which can confirm that the composite electrode material was successfully prepared.
Embodiment 2
[0046] Take 0.3g of MIL-100(Fe), 1.5g of PVDF, and 1.5g of graphite in a 10mL volumetric flask, and pour it into a beaker after constant volume with acetonitrile, stir at 200rpm for 26 minutes, take 1.6mL of the mixed solution and use a metal die Cover evenly on a 4cm×4cm titanium electrode, and dry at 55°C. The section of the finished composite electrode material ( image 3 ) and surface ( Figure 8 ) for scanning electron microscope test, and with the section of pure titanium electrode ( figure 1 ) and surface ( Figure 6 )comparing. Compared with the pure titanium electrode, the surface of the composite electrode material in Example 2 has an obvious MOFs crystal structure, and it can be seen that there is an increased modification layer in the cross section, which can confirm that the composite electrode material was successfully prepared.
Embodiment 3
[0048] Take 0.4g of MIL-101(Cr), 0.5g of PE, and 0.5g of graphene in a 10mL volumetric flask, pour it into a beaker after constant volume with chloroform, stir at 240rpm for 48 minutes, and take 2.5mL of the mixed solution with metal The stamper is evenly covered on the 4cm×10cm titanium electrode, and dried at 66°C. The section of the finished composite electrode material ( Figure 4 ) and surface ( Figure 9 ) for scanning electron microscope test, and with the section of pure titanium electrode ( figure 1 ) and surface ( Figure 6 )comparing. Compared with the pure titanium electrode, the surface of the composite electrode material in Example 3 has obvious MOFs crystal structure, and it can be seen from the cross-section that there is an increased modification layer, which can confirm that the composite electrode material was successfully prepared.
